Fuel delivery valving and hose system

ABSTRACT

Through a series of valves that are preset to control the fuel flow, volume low and high for starting, idling and high maximum RPM engine running. The fuel delivery system is coupled to fuels of choice. Fuels consisting of the following: Liquefied petroleum gas (LPG), compressed natural gas (CNG), liquefied natural gas (LNG), and biogas. It can also be used with a combination of gases and liquefied hydrocarbon fuels.  
     The Fuel Delivery Valving and Hose System is connected to the fuel source with a hose slid over a male barb and clamped in place. The fuel source can be a fuel tank, a fuel tank with a regulator or directly to a fuel line. The hose from the fuel source is connected to the main shut off valve on the inflow side. A piece of hose is connected to the main shut off valve on the outflow side to an inflow tee, the tee allows the fuel to go in two directions simultaneously or separately. The hose connected to the secondary part of the tee goes to the low RPM valve. This valve outflow controls the low volume of fuel for starting and idling. There is a piece of hose connected to tee outflow side to the high RPM run valve inflow. This high rpm run valve is kept shut until the engine is started, then opened to allow a controlled higher volume of fuel to pass through. A piece of hose is connected to the outflow of the high RPM run valve to a second tee. The low RPM run valve is connected to this same second tee by hose. This creates a loop. When the high RPM run valve is off it directs the fuel through the low RPM run valve for starting and idling. The second tee is connected to the high RPM valve by hose. This valve is preset to insure that the maximum controlled amount of fuel is delivered to the injector. The high RPM valve outflow is connected to a hose that is connected to an injector. This injector is tapped directly into a carburetor insulator or intake manifold.

[0001] None of the prior art describes the use of a fuel deliveryvalving & hose system with the unique features provided by the presentinvention. While prior art references disclose engines and machinespowered by gaseous hydrocarbon fuels, none disclose a fuel deliveryvalving & hose system that can be used with such a broad variety offuels.

[0002] U.S. Pat. No. 5,377,646 issued to Ronald E. Chasteen on Jan. 3,1995, discloses a gaseous fuel management system for an internalcombustion engine, but does not teach or suggest it's use with a fueldelivery valving & hose system.

[0003] PCI International Application Number WO 81100282, published onFeb. 5, 1981 discloses a fuel supply system for internal combustionengines using liquefied petroleum gas. It does not teach or suggest theuse of a delivery valving & hose system that can deliver CNG, LNG, LPG,Biogas, and other kinds of gaseous fuels.

[0004] PCI International Application Number 1,158,934 published on May29, 1992 discloses a dual fuel injection system and a method ofcontrolling such a system. The first fuel may be gasoline and the secondfuel may be liquefied gas.

[0005] It may be seen that none of the above mentioned referencesteaches the use of a fuel delivery valving & hose system that candeliver gaseous or liquefied fuels to a two or four stroke engine(s)reciprocating engine(s) or internal combustion engine(s), but can beused with a broad spectrum of engines and thermo-technologies. Forexample: generators, motorized concrete buggies/georgia buggies, floorbuffers, asphalt or concrete scarifiers/planes, concrete grinders, trashpumps, air compressors, paint sprayers, trowel machines, scissor lifts,boom lifts, light towers, compacting tampers/rollers, tractors, bobcat,steer loaders, backhoes, ditch witch, log splitters, cars, trucks, aircraft, and motorcycles.

[0006] The fuel delivery valving & hose system can be operated bycomputer or manually. The fuel delivery valving & hose system can usetwo or more fuels at the same time.

[0007] The fuel or fuels being delivered to the power plant through thefuel delivery valving & hose system can be shut off manually for safety,can be shut off automatically by the use of a solenoid or vacuum switchto stop the flow. The fuel is shut off when the power plant/engine shutsdown due to low oil or mechanical failure.

[0008] It is an object of the invention to provide improved elements andarrangements there of in an apparatus for the purpose described which isdependable and fully effective in accomplishing it's intended purposes.

[0009] These and other objectives of the present invention will bereadily apparent upon further review of the following specifications anddrawings.

PRIOR ART

[0010] None discloses the means to move fuel from a fuel supply sourcethrough a low/high valving system to an engine/power plant

SUMMARY OF THE INVENTION

[0011] The present invention is an assembly of valves, hoses andcouplings, coupled together to a fuel source at the inflow and coupledto an injector/carburetor/carburetor insulator at the engine/powerplant.

[0012] An object of the invention is expected to allow a two or fourstroke engine/power plant(s) to run at a low and high RPM with less fuelconsumption, using a single or multi gaseous or hydrocarbon fuels.

[0013] It is also expected that it will provide a minimum amount of fuelfor starting and idling and a minimum amount of fuel consumption forrunning at higher RPM.

[0014] It is also expected that the present invention will be highlyefficient at regulating and controlling gaseous fuels supplied to theengine, for cleaner emissions.

[0015] It is an objective of the invention to provide an improvedapparatus that is safe, dependable, inexpensive and fully effective inaccomplishing its intended purpose/purposes as described.

[0016] These and other objects of the invention will become readilyapparent upon further review of the following specifications anddrawings.
